Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a waterproof electric controller light touch switch. Background Art

[0002] The touch switch, also known as the push button switch, first appeared in Japan and is called a sensitive switch. When in use, the switch function is closed by applying pressure in the direction of the switch operation under the condition of the operating force.
